REENFORGED CONCRETE.

Application filed November the said purpose and it is the object oft' my present invention to provide an improved reentorcement ot the type utilizing spiral springs, the said reentorcement being' selt supporting so that it can he readily transported7 assembled and embedded in the concrete.

The invention comprises the in'iproved combination and arrangement ot parts hereinafter described and claimed. i

Referring to the accompanying` sheet explanatory drawings Figure l is an elevation and Figure a plan view of a reentorcement in accordance with any invention.

The reenicorcement comprises ot rows ot spirals e, each woven with the spirals at` its opposi e sides and the spirals in one row 1lieinn inte woven. with the'spirals in the adjacent rows. i1 stri'lcture so arranged has the disadvantage that it does not maintain itself in the eX- tended condition shown in the plan vView hut the coils or spirals can close on one another. To overconie this defect, l interweaye small diameter coils or spirals into two adjacent rows ot `spirals at the point where the latter are themselves interwoven. In the drawings small coils or spirals I) are inter` woven with adiacent rows ot coils e. in

Figure l, the positions ot the small inter-- 14, 1925. Serial No, 69,165.

weaving coils or spirals between the second and third rows of spirals a are shown hy the dot and dash figures c.

Rows of interwoven spirals a having the small interwoven coils o torina mattress and several mattresses can he connected together hy intermeshing connecting coils e with the end coils ot the vmattresses andV threading rods or hars Z through the intermeshed coils as shown. The connecting coils e are ot opposite hand to the coils they connect.

The coiled mattresses have the concrete formed therearound in any Vordinary man-A ner, hut because ot the employl'nent of my invention, the correct extension or spacingl et the rows oit coils during concreting is ensured, and therefore a satisfactorily reentorced wall. or like part is produced.`

Y l. A reenforcernent for concrete coniipris ing, in combination, a plurality of interwoven rows ot interwoven spirals and means bindingl the rows together at places ot interengagement. v

2. A reen'torcement 'for concrete compris 65 ing, in combination, a plurality ot' intern woven rows ot interwoven spirals and spirals interwoven with the raid rows at the places ot inter-engagement.

3. A reentorcement for concret-e consisting' '70 oit a plurality ott reentorcements claimed in claim l, and'means for interconnecting the reentorcements including' spirals inter n'ieshing; with the end spirals ot the iwoven rows, and rods threaded thro, h intermeshing spirals.

.In testimony whereof lhavc signed my name to Vthis specification.
